easy📝 Conceptual Q2 of 15
Computer Networks - OSI and TCP/IP Models
During decapsulation, what happens to the headers added during encapsulation?
AHeaders are added again
BHeaders are encrypted
CHeaders are removed one by one
DHeaders are ignored
Step-by-Step Solution
Solution:

  1. Step 1: Define decapsulation

    Decapsulation is the process of removing headers from data as it moves up the network layers.

  2. Step 2: Match options to definition

    Removing headers one by one matches decapsulation; adding headers or ignoring them is incorrect.

  3. Final Answer:

    Headers are removed one by one -> Option C

  4. Quick Check:

    Decapsulation = Removing headers [OK]
Quick Trick: Decapsulation removes headers going up layers [OK]
Common Mistakes:
MISTAKES
  • Thinking headers are added during decapsulation
  • Confusing decapsulation with encryption
  • Ignoring the order of header removal
